Studies are showing that smokers are more likely than nonsmokers to lose teeth.  

Current smokers were 2.5 times as likely to have lost all of their teeth as people who never smoked. Former smokers were 1.5 times as likely to have lost all of their teeth.

Even people who had quit smoking 30 years ago were at increased risk for tooth loss.

The more cigarettes a day someone smoked, the higher the risk for tooth loss. The highest risk was among current smokers who smoked 25 or more cigarettes a day. It was lower for those who smoked 1 to 14 cigarettes a day.

This pattern held in former smokers, too. Those who had smoked the most cigarettes in the past were almost twice as likely to have lost all of their teeth as those who had smoked the fewest. The time a person had smoked also mattered. Risk of tooth loss was highest for people who had smoked 50 years or more. It was lower for people who had smoked for 35 years or fewer.

Exposure to environmental tobacco smoke also increased the chances of tooth loss. People who had never smoked were 1.22 times as likely to lose teeth if they were exposed 1 to 5 hours a week to someone else's smoke. This went up to 1.37 for people who were exposed for 6 or more hours a week.
